U dont need to answer Question 1

QUESTION 1 COVID-19 and Monetary Policy in the IS-LM Model. Consider the following model of the goods market in a closed economy, where s measures the extent of the spread of Covid- 19 within the country: Z = C+1+G (1) Planned aggregate expenditure C - 5+ (0.8 - s) Yo (2) Consumption function (3) 1=2-s+0.2Y - 100i Planned investment (4) G =2+s Government expenditure Yo = Y - T (5) Disposable income T = 0.ZY (6) Tax function Y = Z (7) Equilibrium Condition and money market: (8) Money demand L = 5 + s + 0.125Y - 200i M M (9) Money supply P (10) Money market equilibrium Using the above model and rounding to 5 decimal places, solve for the equilibrium output y * when: There is no covid-19, i.e. s = 0, and money supply ~ = 5QUESTION 5 Using the model in Question 1 and rounding to 5 decimal place; solve for the equilibrium output Y' when: The economy is affected by could-19 with s = 0.2, but the RBA conducted expansionary monetary policy and money supply is increased to g: T. QUESTION 3 Using the model in Question 1 and rounding to 5 decimal place; solve for the equilibrium output t' :'when: The economy is affected by could-19 with s = 0.2, but money supply remains at g: 5 QUESTION 4 Using the model in Question 1 and rounding to 5 decimal place; solve for the equilibrium interest rate i\
